SDK Preview is only officially supported on Visual Studio 2017, and while you can install it in a production environment, your app needs to be targeted to Creator Update or earlier to submit it to the Windows Store. There are a few known issues to be aware of:

Designer Fails To Do: When you see XAML in the Visual Studio Designer Window, the controls fail to do. This can be solved by using Visual Studio 2017.3 Preview.

Compilation Fails on Platforms Without Windows 10 When you create apps on previous platforms, you may get a build error:

This will happen if the minimum target platform version is set to 10.0.16225.0. To bypass this, right-click on your project file and select properties or open your project file in your favorite editor and change the version to a previously released SDK. For example: 10.0.10586.0

ecmangen.exe Removal from SDK: Ecmangen.exe is no longer sent together with Windows SDK. Developers who trust ecmangen for event manifest creation are recommended to install Windows Creators Edition by SDK to retrieve the file. Developers can also use note pad or other XML editor for choice for manifest creation. A schema file is available on MSDN to help with manifest creation, for tools that support it.
